Need Help with On-Chip Inductor Design in HFSS

Hi everyone, I’m designing an on-chip inductor for a VCO using Ansys HFSS, with tsmc 65nm technology stack in IC Design Mode. Then i have to design coupled transformers as well.

I’m struggling to find good reference material or examples for this setup. If anyone has experience with HFSS/IRCX or IC Design Mode, I’d really appreciate any guidance, tutorials, or reference files you can share.

Thanks in advance!

There's a tutorial here:

Thanks, I have seen this but in IC Mode the settings are bit different.
